Estou desenvolvendo um aplicativo para iPhone usando o objetivo-c. A notificação por push básica está funcionando corretamente. Agora, quero adicionar uma notificação avançada no meu aplicativo, mas não consigo disparar o didReceiveNotificationRequest no NotificationService.

Aqui está a carga útil da notificação que recebo no Appdelegate:

Aqui está o arquivo NotificationService.m;

#import "NotificationService.h"
#import "Common.h"

@interface NotificationService ()

@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;

@end

@implementation NotificationService

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];
NSLog(@"didReceiveNotificationRequest");
// Modify the notification content here...
// load the attachment
NSDictionary *userInfo = request.content.userInfo;
NSString *imageURL = [userInfo valueForKey:@"thumbnail_image"];
NSArray *parts = [imageURL componentsSeparatedByString:@"."];
NSString *extension = [parts lastObject];
[self loadAttachmentForUrlString:imageURL
                        withExtension:extension
               completionHandler:^(UNNotificationAttachment *attachment) {
                   if (attachment) {
                       self.bestAttemptContent.attachments = [NSArray arrayWithObject:attachment];
                   }
                   //self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]", self.bestAttemptContent.title];

                   self.contentHandler(self.bestAttemptContent);
               }];



}

- (void)serviceExtensionTimeWillExpire {
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
self.contentHandler(self.bestAttemptContent);
}

- (void)loadAttachmentForUrlString:(NSString *)urlString withExtension:(NSString *)extension completionHandler:(void(^)(UNNotificationAttachment *))completionHandler  {

__block UNNotificationAttachment *attachment = nil;
NSURL *attachmentURL = [NSURL URLWithString:urlString];

NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session downloadTaskWithURL:attachmentURL
            completionHandler:^(NSURL *temporaryFileLocation, NSURLResponse *response, NSError *error) {
                if (error != nil) {
                    NSLog(@"%@", error.localizedDescription);
                } else {
                    NSFileManager *fileManager = [NSFileManager defaultManager];
                    NSURL *localURL = [NSURL fileURLWithPath:[temporaryFileLocation.path stringByAppendingString:extension]];
                    [fileManager moveItemAtURL:temporaryFileLocation toURL:localURL error:&error];

                    NSError *attachmentError = nil;
                    attachment = [UNNotificationAttachment attachmentWithIdentifier:@"" URL:localURL options:nil error:&attachmentError];
                    if (attachmentError) {
                        NSLog(@"%@", attachmentError.localizedDescription);
                    }
                }
                completionHandler(attachment);
            }] resume];
}

@end

o que estou perdendo?

Conselho por favor,
